Can geraniums repel mosquitoes?

Geraniums can repel mosquitoes. Geraniums that can repel mosquitoes are geraniums with incense leaves, which, as their name implies, can emit fragrance, such as nocturnal incense, jasmine and rosemary, as well as geranium, which also belongs to geranium. The aroma emitted can not only beautify the indoor environment and purify the indoor air, but also repel mosquitoes, but scientists have not given a specific explanation for this, but we just need to know. Fragrant leaf geranium does have the effect of repelling mosquitoes.

Culture method of geranium

1. Soil: geraniums require fertile soil with good drainage. Pot soil can be mixed with rotten soil, rice chaff ash and garden soil, and then mixed with a small amount of superphosphate.

2. Watering: geraniums are resistant to drought and afraid of stagnant water. Therefore, in the process of growth, water should be properly controlled. Too much watering, basin soil water content is too large, will cause overgrowth or rotten roots. When the spring and autumn growth and flowering is exuberant, it can be watered more appropriately, but it should also be appropriate to keep the basin soil moist. If the temperature is low in winter and the plant grows slowly, it should be watered as little as possible.

3. Fertilization: in cultivation, in addition to applying sufficient base fertilizer, thin liquid fertilizer can be applied every 7-10 days in the growing season, especially in the peak flowering period. It is better to dilute with rotten livestock and poultry manure with water, and it can also be poured with rotten cake fertilizer. 3-5 days before fertilization, little or no watering, watering when the basin soil is dry, is more beneficial to root absorption.

4. Lighting: pelargonium is native to South Africa and likes the environmental conditions with plenty of sunshine, warmth and good ventilation. Under the condition that the light is not too strong in spring and early summer, the flowerpot can be placed in a place with sufficient light to receive sufficient light, but in the hot season of midsummer and early autumn, it is appropriate to put it in a shaded place to avoid strong light, otherwise, the branches and leaves will be burned.

5. Pruning: in order to make the plant beautiful and blossom, thinning and pruning can be carried out if the plant grows too vigorously in spring. Cut off the residual flowers and over-dense branches in time after flowering. The dormant period is also pruned once, the yellowed old leaves are cut off, the overdense branches are thinned, and the overlong branches are cut short, so that after the dormant period, new branches are produced and buds continue to blossom. In addition, the geranium itself has a special smell and rarely suffers from insect pests. Therefore, there is no need for prevention and control.
